To all whom it may concern:

Be it known that 1, WILLIAM F. Mir-incline a citizen of the UnitedStates, and a resident of the city of New York, (loney island borough ofBrooklyn, in the county of Kings and State of New York, have invented anew and Improved Gun-ll lount, of which the following. is a full, clear,and er ct description this being a division'of the application forLetters Patent for a ma chine-gun for shooting-galleries, Serial No.226,222, filed by me April 2, 1918.

' The object of the invention is to provide a new and improved gun mountfor machin guns for shooting galleries arrr ed t- 1 't the pointingmovement of the un to vent damage to the side WW 9 ceiling floor of theestablishment or iniury to bystanders. Another object is to counrbalance the gun with a view to enaole the user to readily move the gunabout for aiming purposes.

With these and other objects in invention consists of certain new ofconstruction hereinafter I I described and then specifi ally'pointed outin the claims. r

A practical embodiment of the invention is represented in the accompan Tings forming a part of this specification, in which similar charactersof reference indicate corresponding parts in all the 'ews.

Figure 1 is a side elevation of the machine gun;

Fig. 2 is an enlarged sectional rea tion of the same on the line c Fig.3 is an enlarged sectional plan of the same on the line 3 of Fig. 1 andshowing more pz't-rticularly the means for limiting the sidewiseswinging of the gun;

Fig. 4: is an enlarged sectional side eleration of the machine gun withparts in position for firing; and

Fig. 5 is a sectional the same on the line 55' of ig.

The frame 20 of the machine gun is pro front elevation of vided with asuitable gun stool: 21 and a barrel receiver 22 in which is held abarrel 23. On the frame 20 is mounted to rotate intermittently amagazine 32 adapted to hold cartridges 45 adapted to register with thebore of the barrel 23 and adaptedto be successively fired by a firingpin 50 controlled by a hammer 106 actuated by a cam movement with 1173upper end on a flange -wheel 111 secured on a shaft .73 adapted to be.turned by a crank arm 80. The shaft 73 journaled in bearings 74: and 75formed on the frame 29. c

in order to permit the user to swing the gun around during the firingoperation with r 1 of hitting different targets in the shootin o-allery,use is made of a gun mounting arranged as follows: A base 130 i asuitable stand at the front "rooting gallery, and in this base ivertically adjust-able sleeve 181 adapted to be raised or lowered andfastened in place by clampingthe upper. end of the base around thesleeve 131. For this purpose the up'perend of the base 130 is providedwith a'vertical slit 132 and lugs 133 and arranged on oppositesides ofthe slit and engaged by a clamping screw 135 which when loosened permitsup and down n oveiuent of thesleeve 131. W hen the desired adjustment ofthe sleeve 1%1 has been made the clamping screw 135 is screwed up toclamp the sleeve in place in the upper endof the'basc 130. in the upperend of the sleeve 131 is mounted to turn a cylindrical neck 140depending from a head 141-1 resting the top edge of the sleeve 131. Thehead is p ded on opposite sides with. beanings 1&2 and 1&3 in which aremounted to turn the trunnions or bearings Tstand 75 previously mentionedand formed on the sides of the casing20. The lower end 141-5 0 20 isarranged a pivot 1-1-6 ened by the eye 147 of a rod l48extend downwardin the neck 140. A spring is coiled on the red lid-8 and is seated 151formed the head 1.41, and the lower end of the 7 By the arrangementdescribed the spring 150 exerts a downward pull on the casing 20 to holdthe bearings 74 and 75 in ment of the frame 20 in either direction thuspreventing the user of the gun from pointing too far upward or too fardown ward to avoid hitting the ceiling or floor of the shooting galleryby the bullets. It will be noticed that the stop screws and 161 can bescrewed farther in or farther out to correspondingly increase ordiminish the up or down swinging movement of the frame 20, and the saidstep screws 160 and 161 are provided with jam nuts 162 and 168 to lockthe stop screws in place after the desired adjustment has been madeaccording to the size of the gallery. It will also be noticed that thehead 141 is mounted to turn in the sleeve 131 and in order to limit thisturning movement of the head, use is made of stop screws 165, 166screwing in lugs 16?, 168 formed on the upper end of the sleeve 131. Theinner ends of the stop screws and 166 are adapted to be engaged by a lug169 attached to or forming part of the head 1451. It will be seen thatby the arrangement described the turning movement to the right or theleft of the gun is limited by the lug 169 abutting against either of theinner ends of the stop screws 165 and 166, and the latter may be screwedin or screwed out to increase or decrease the range of the turningmovement of the gun, and when the desired adjustment has been made thestop screws are locked in place by jam nuts 170 and 171. It isunderstood that by the arrangement described the user of the gun is notliable to point the gun too far in a sidewise direction for the bulletsfired by the gun to strike the side walls of the shooting gallery.

In order to hold the neck 1 10 of the head 1 1 1 from being lifted outof the sleeve 131, use is made of set screws screwing in the sleeve 131and engaging an annular groove 176 formed in the peripheral face of theneck 1%:

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent 1. A machine gun for shooting galleries, comprising abase, a vertically adjustable concaie head carried by the base andmounted to turn, a gun frame mounted to oscillate on the head and havinga cylindrical lower end fitting in the concavity of the head, said framebeing provided with a stock and a barrel, a spring connection betweenthe cylindrical end of the gun frame and the head, a magazine mounted onthe gun frame and coacting with the barrel, means for limiting theoscillating movement of the gun frame, and means for limiting theturning movement of the head.

2. In a. gun mount, a base, a vertically adjustable member carried bythe base, a concave head mounted to turn in the member, a gun framemounted to oscillate on the head and having a cylindrical lower endfitting in the concavity of the head, and a spring connection betweenthe cylindrical end of the gun frame and the head.

3. In a gun mount, a base, a sleeve vertically adjustable in the base, ahead mounted to turn in the sleeve, adjustable means for limiting theturning movement of the head in the sleeve,a gun frame, means forpivotally connecting the gun frame with the head, a spring connectionbetween the gun frame and head, and adjustable means for limiting theoscillating movement of the gun frame on the head.

4. In a gun mount, a base, a head having a concave upper end andbearings at opposite sides, the head being provided with a neck turningin the base, a gun frame having a cylindrical lower end fitting in theconcavity of the head and provided with trunnions engaging saidbearings, a rod pivoted to the cylindrical portion of the gun frame andextending into the neck of the head, and a spring on the rod and seatedon said head.

5. in a gun mount, a base, a head having a neck mounted to turn in thebase, a gun frame mounted to oscillate on the head, a rod pivoted to thegun frame and extending into the neck of the head, a spring on the rodand engaging with its upper end the head, and oppositely arranged screwsin the head and adapted to engage the said rod.

6. In a gun mount, a base, a sleeve adjustably mounted in the base, andprovided with oppositely arranged lugs, a head mounted to turn in thesleeve and having a lug projecting between the lugs of the sleeve,screws in the lugs of the sleeve and adapted to engage the lug of thehead, a gun frame, means for pivotally connecting the gun frame with thehead, and a spring connection between the gun frame and head.
